In a coordinated international operation led by the U.S. DOJ, the notorious 911 S5 botnet was dismantled, resulting in the arrest of its administrator, YunHe Wang, a 35-year-old national of China and a citizen of St. Kitts and Nevis by investment. The botnet, which infected over 19 million IP addresses, was used to facilitate billions of dollars in pandemic and unemployment fraud, cyber-attacks, child exploitation, harassment, bomb threats, and export violations.
